Bun cha is a Hanoian specialty distinct from the pho and banh mi that get most of the international attention: grilled pork patties and sliced pork belly served in a bowl of light dipping broth alongside a plate of vermicelli noodles and a tray of fresh herbs. You combine them yourself at the table, dipping the noodles and herbs into the broth. Huong Lien has been serving it from this narrow building on Le Van Huu Street since long before anyone photographed presidents eating here.
The "combo Obama" is exactly what you'd expect: bun cha, nem ran (fried spring rolls), and a Hanoi beer. The restaurant now operates on several floors to accommodate demand, and the ground floor — where the famous meal happened — is always the most crowded. Despite the celebrity status, the food is honest and the price remains accessible. Come for lunch rather than dinner; bun cha is a midday meal in Hanoi and the kitchen is at its best between 11am and 2pm.
